SOX2 is one of the members of the SOX transcription factor family, which is believed to be an important transcription factor that plays a role in embryonic development, maintenance of stem cells, cancer progression, and resistance to cancer treatment. There is increasing evidence suggesting that SOX2 is crucial for the initiation, progression, invasion, metastasis, and treatment resistance of prostate cancer, therefore understanding the mechanism of SOX2 in prostate cancer can provide better targets for the treatment of prostate cancer. This article reviews the structural domains, normal physiological functions, and role in prostate cancer progression of SOX2, providing potential targets for prostate cancer treatment.

In addition, it has been suggested that BST2 is highly expressed in various types of human cancer and high BST2 expression is related to different clinicopathological parameters in cancer. The molecular mechanism underlying BST2 as a potential tumor biomarker in human solid tumors has been reported on; however, to the best of our knowledge, there has been no review published on the molecular mechanism of BST2 in human solid tumors.

Herein, FeN/CN nanosheets rich in nitrogen vacancies are developed for high-performance redox dyshomeostasis therapy after surface conjugation with polyethylene glycol (PEG) and cyclic Arg-Gly-Asp (cRGD). Surface defects in FeN/CN serve as electron traps to drive the directional transfer of the excited electrons to Fe atom sites under ultrasound (US) actuation, and the highly elevated electron density promote the catalytic conversion of HO into ·OH.

Human endogenous retroviruses (HERVs) have evolved from exogenous retroviruses and account for approximately 8% of the human genome. A growing number of findings suggest that the abnormal expression of HERV genes is associated with schizophrenia, multiple sclerosis, endometriosis, breast cancer, bladder cancer and other diseases. HERV-W env (syncytin-1) is a membrane glycoprotein which plays an important role in placental development.

Purpose: To explore the effect of role reversal and standardized patient simulation on the training of new nurses.
Method: This study was conducted in a territory hospital in China between August 2021 and August 2022. The selected staff were all newly recruited and trained nurses, with a total of 58 cases.
Energy band structure of inorganic nano-sonosensitizers is usually optimized by surface decoration with noble metals or metal oxide semiconductors, aiming to enhance interfacial charge transfer, augment spin-flip and promote radical generation. To avoid potential biohazards of metallic elements, herein, metal-free graphitic carbon nitride quantum dots (g-C N QDs) are anchored onto hollow mesoporous TiO nanostructure to formulate TiO @g-C N heterojunction. The direct Z-scheme charge transfer significantly improves the separation/recombination dynamics of electron/hole (e /h ) pairs upon ultrasound (US) stimulation, which promotes the yield of singlet oxygen ( O ) and hydroxyl radicals (·OH).

Herein, a dual plasmonic Au/SF@CuS nanoreactor (abbreviation as ASC) is elaborately developed by covalent immobilization of sulfur defective CuS nanodots onto the surface of silk fibroin (SF)-capped Au nanoparticles. Tumor hypoxia can be effectively alleviated by ASC-mediated local oxygenation, owing to the newfound catalase-mimic activity of CuS.

The expression of FBXW7 is controlled by multiple pathways at different levels. FBXW7 facilitates the maturity and function maintenance of immune cells functioning as a mediator of ubiquitination-dependent degradation of substrate proteins.

Background: Nowadays, biological tissue engineering is a growing field of research. Biocompatibility is a key indicator for measuring tissue engineering biomaterials, which is of great significance for the replacement and repair of damaged tissues.
Methods: In this study, using gelatin, carboxymethyl chitosan, and sodium alginate, a tissue engineering material scaffold that can carry cells was successfully prepared.
Disturbance in redox homeostasis always leads to oxidative damages to cellular components, which inhibits cancer cell proliferation and causes tumor regression. Therefore, synergistic effects arising from cellular redox imbalance together with other treatment modalities are worth further investigation. Herein, a metal-organic framework nanosystem (NMOF) based on coordination between Fe (III) and 4,4,4,4-(porphine-5,10,15,20-tetrayl) tetrakis (benzoic acid) (TCPP) was synthesized through a one-pot method.

Surface mineral of MnCaP can be degraded under mild acidity, leading to the release of both Mn and AIPH. The leached Mn not only facilitates chemodynamic therapy (CDT) via hydroxyl radicals ( OH) from Mn -mediated Fenton-like reaction but also acts as contrast agent for magnetic resonance imaging.

Here, we study the cross-talk between phosphoinositide 3-kinase (PI3K) and Ras signaling during lacrimal gland budding morphogenesis. Our results show that PI3K is activated by both the p85-mediated insulin-like growth factor (IGF) and Ras-mediated fibroblast growth factor (FGF) signaling.

How multiple receptor tyrosine kinases coordinate cell fate determination is yet to be elucidated. We show here that the receptor for platelet-derived growth factor (PDGF) signaling recruits the p85 subunit of Phosphoinositide 3-kinase (PI3K) to regulate mammalian lens development. Activation of PI3K signaling not only prevents B-cell lymphoma 2 (BCL2)-Associated X (Bax)- and BCL2 Antagonist/Killer (Bak)-mediated apoptosis but also promotes Notch signaling to prevent premature cell differentiation.
